Patent CA-2077457-A1 (CA)
Title: Multi-stage reforming process
Inventor: MULASKEY BERNARD
IPC: C10G59/02
Filed: 1991-02-28
Abstract: A multi-stage reforming process is described in which a conventional reforming catalyst (12) is used upstream of an intermediate pore size crystalline silicate containing a Group VIII metal (14).  The conventional catalyst is operated at typical reforming conditions and the crystalline silicate is operated at lower pressures. At least a portion of the hydrogen and substantially all of the hydrogen sulfide present is removed (18) from the penultimate stage reformate before it is used in the feed to the final stage.
Patent CA-2079425-A1 (CA)
Inventor: INGRAM KEITH W
IPC: B29C48/29
Filed: 1992-09-29
Abstract: The method of compression molding an article such as a closure wherein a thermoplastic resin is mixed with additives including a metallic pigment additive, extruded through a nozzle, cut by a blade into individual pellets, and each pellet is deposited into the cavity of a mold which is then closed to compression mold the pellet into an article, including the step of adding a blowing agent to the resin prior to extrusion in a quantity sufficient to randomize the metallic particles in the metallic pigment additive such that gaseous bubbles are provided in the extruded melt and that the gaseous bubbles are substantially expelled during the compression molding resulting in an article that is substantially free of blemishes which normally occur. Preferably, the method includes positioning a mixer plate in the path of the resin immediately prior to the nozzle.
Patent CA-2081166-A1 (CA)
Inventor: BALES BRUCE M
IPC: H04M3/42
Filed: 1992-10-22
Abstract: A communication switching system having a plurality of switching nodes in which each switching node upon initialization completely establishes its own internal configuration. This establishment of internal configuration includes the number and type of switching modules and within each switching module: type of module control processor, type of internal switching network, printed board carriers, type and number of auxiliary circuits, and type and number of link interfaces. Each unit of a switching module reports relevant information to the module control processor; and in turn, the module control processor reports its own information and the information of the other units to a node processor (the main processor within a switching node). Further, each switching node and interfaces of the switching node automatically identifies the other switching nodes connected by communication links and switching paths to those switching nodes. Each interface upon being initialized automatically performs low level initialization operations over the connected link with the far end interface. The interfaces then report the completion of the initialization operations to the connected switching nodes. Upon receiving thesereports, each switching node becomes aware of the existence of the links to other switching nodes. Each switching node then exchanges node numbers with the far end switching node connected via interfaces and communication links to establishthe hierarchy of switching nodes in the switching system.

Title: Procedure for detecting and preparing anti-ige autoantibodies and use of these antibodies as active agents in diagnostic and therapeutic compositions
Inventor: DE WECK ALAIN
IPC: G01N33/564
Filed: 1991-05-10
Abstract: In a procedure for detecting free or complexed anti-IgE  autoantibodies, samples, especially human blood, are contacted and incubated with IgE material in form of IgE-antibodies, IgE peptides or recombinant IgE fragments bound on a solid carrier. The procedure can be carried out as a direct assay, as a sandwich assay or as a competitive assay. The procedure is useful in a method for preparing anti-allergic human anti-IgE antibodies having therapeutic blocking activities in allergic diseases. In this method a human body fluid having a content of anti-IgE autoantibodies is selected according to the above procedure and the immunoglobulin in the fluid is concentrated, preferably by alcohol fractionation or by ion exchange chromatography. For obtaining pure anti-IgE  autoantibodies, they are isolated from the concentrated product by affinity chromatography. The anti-IgE antibodies and complexes thereof are useful as active components in pharmaceutical compositions for the treatment of allergic diseases. The formation of auto-anti-IgE antibodies can be induced in vivo by IgE-peptides or recombinant IgE fragments.

Title: Method and apparatus for reproducing blended colorants on an electronic display
Inventor: ADAMS LOUIS W JR
IPC: G01J3/46
Filed: 1993-03-05
Abstract: An apparatus and method for reproducing the color of blended colorants on an electronic display such as a cathode ray tube, liquid crystal display or other type of electronic device that utilizes RGB values. Predictions of blended colorants on or in substrates can be made from XYZ measurements of samples prepared with no colorants, one colorant, and pairs of colorants. The calculation method uses light absorption, light scattering, and light absorption blend coefficients.      An image digitizer can be used to obtain XYZ values from samples.      Furthermore, image digitizer RGB values are converted into XYZ values with a non-linear model using a simple method. Furthermore, the above process to generate XYZ values from image digitizer RGB values can be used to generate RGB values from XYZ values for electronic display.

Title: Method and apparatus for establishing a communication link
Inventor: BUCHENHORNER MICHAEL J
IPC: H04B7/005
Filed: 1992-06-05
Abstract: A method and apparatus whereby a communication unit (10) transmits a first communication channel request signal at a first power level. If a communication link with a base site (12) is not established within a predetermined period, the communication unit transmits a second communication channel request signal at a second level which is higher than the level of the first communication channel request signal. This process may be continued for a predetermined number of times or until a communication link is established. Thus, the probability that a nearby base site, rather than a more distant site, grants the communication channel is greatly enhanced.

Title: Method of installation of composite electrodes in discharge lamps
Inventor: WOODWARD DAVID R
IPC: H01J61/067
Filed: 1993-08-06
Abstract: ABSTRACT: "A method of installation of composite electrodes in discharge lamps"     A method of electrically connecting and securing a composite discharge electrode in an electric gas discharge lamp. A composite discharge electrode is held against a metallic lead-through conductor. A beam of laser light is directed onto a region of the lead-through immediately adjacent the electrode to form a pool of molten metal which wets the composite electrode. The beam of laser light is then removed such that the pool of molten metal solidifies and coalesces with the lead-through and the electrode. The resultant weld provides a good electrical, as well as a physical,connection and permits the use of prefabricated composite sintered discharge electrodes without integral leads along with conventional lead-through wires of the type conventionally used in gas discharge lamps.

Title: Tamper-proof sealing plug assembly
Inventor: TISON MARC
IPC: B65D55/02
Filed: 1993-09-02
Abstract: A plastic tamper-proof sealing plug assembly for use in securely sealing the valve outlet of a pressurized bottle or any other type of container. The tamper-proof assembly has a tubular gasket provided with a central opening, sized to fit into and seal a valve outlet, and a sealing plug element with a plug projecting from it, which is sized to snugly fit into the tubular gasket in order to close the valve outlet. The tamper-proof assembly also has a security seal in the form of a strap that has one end attached to one side of the sealing plug element and also has another free end. The strap projects outwards from the side of the sealing plug element and is long enough to surround the valve. The tamper-proof assembly further has a fastener for irreversibly fastening the free end of the strap to the sealing plug element so that the strap must be broken in order to remove the plug and the gasket if necessary, from the valve outlet. This gives a visible indication to anyone using the bottle that the plug and the gasket have previously been removed or tampered with. This assembly may also consist of a moulded, one-piece tamper-proof assembly where the gasket and the sealing plug element are combined together in a combined gasket and sealing plug element unit.      However, when the gasket and the sealing plug element are moulded into a one-piece tamper-proof assembly, they are separated from one another before they are installed on the valve outlet.
